(3) Judging the type of the mobile phone positioning request, determining whether the positioning request needs to be sent according to different request types, selecting a corresponding mobile phone positioning platform according to the mobile phone number for the request needing to be sent, and sending the mobile phone positioning platform to the positioning interface server.
The present invention classifies location requests into the following categories: passive positioning request, active positioning request and continuous positioning request; wherein,
passive positioning: after the alarm person dials the alarm call, the alarm person is confirmed to be a real alarm by the command center or automatically and directly inquires the position information of the alarm mobile phone through the positioning system.
Active positioning: and initiating a positioning request by the command center aiming at some specified numbers, and positioning the numbers by the positioning system.
Continuous positioning: belongs to one of the active positioning requests, and is a special application of the active positioning request. When the police department needs to track the whereabouts of certain specific persons in real time, for example: VIP in the white list, special protection crowd, criminal suspects in the black list or persons being kidnapped can appoint a positioning number through staff, set continuous positioning time intervals, and continuously position the number of the specific person, so that the position condition of the tracked person can be timely mastered.
Judging whether the received positioning request is an active positioning request or not, if not, judging whether the received positioning request is a repeated request or not, if so, not sending the positioning request but directly returning a last query result without sending the positioning request and if the repeated time is within a set time, selecting a mobile phone positioning platform according to a mobile phone number and sending the mobile phone positioning platform to a positioning interface server; the set time can preset a time value according to the requirement, such as 15 minutes, and the repeated passive request which does not exceed 15 minutes is not sent outwards but directly returns the last query result;

(5) The positioning interface server judges whether idle positioning resources exist or not, and if not, the request is added into a waiting sending queue; if yes, judging that the authentication needs to be waited. Because the current successful positioning needs to pass the authentication, the system sets that the positioning is allowed only by the mobile phone which dials the security phone. The authentication requires a certain time, and the positioning request sent before the authentication will fail, so that the positioning request may need to be sent after the authentication is passed. For the request which does not need to wait for authentication, a mobile phone positioning request is sent to the selected mobile phone positioning platform through a positioning interface server; and adding the request needing to wait for authentication into a waiting sending queue.
(6) And after the request of the queue to be sent is equal to the request of the queue to be sent and idle positioning resources are obtained, the request is sent to the selected mobile phone positioning platform through the positioning interface server according to the priority sequence of the request.
The priority order is continuous positioning request priority > active positioning request priority > passive positioning request priority.
The above is the positioning request receiving and sending process of the mobile phone positioning method of the present invention.
